Extended Data Fig. 4: Comparison between Melt Inclusion (MIs) and whole-rock compositions for Kilauea volcano.
From: Carbon concentration increases with depth of melting in Earth’s upper mantle
Sr/Nd and Sr/Sm ratios (upper panels) are overlapping for the two datasets, and show no dependence on magma differentiation degree (SiO2, in wt. %). The dashed vertical line indicate 52 wt. % SiO2, the threshold below which data are considered for calculating the “mean” compositions. The bottom panels compare the mean Ba (left) and Nb (right) contents (from averaging of all < 52 wt. SiO2 data; red triangle) with the inferred parental melt contents (from averaging the most primitive products only; yellow triangle). Both data types are listed in Extended Data Table 2.
